Abstract Colloidal photonic crystals and materials derived from colloidal can exhibit distinct structural colors that result incomplete band gaps. Through rational design, the of such be tuned reversibly by external physical chemical stimuli. Such stimuli include solvent dye infiltration, applied electric or magnetic fields, mechanical deformation, light irradiation, temperature changes, changes in pH, specific molecular interactions. Reversible color alterations lattice spacings, filling...
Carbon quantum dots (CQDs) are novel nanostructures that have great potential as fluorescent markers due to their multi-fluorescence, down and up converted emission, resistance photobleaching, biocompatibility. Here, we report the synthesis of CQDs by submerged arc discharge in water method. We discuss method's simplicity, natural phases’ separation, scalability. The produced size distribution was range 1–5 nm. High-resolution transmission electron microscopy images fast Fourier...
Poly(methyl methacrylate) (PMMA)-based colloidal photonic crystals have an incomplete band gap (PBG) and typically appear iridescent in the visible range. As powders, synthetic PMMA opals are white, but when infiltrated with carbon black nanoparticles, they exhibit a well-defined color that shows little dependence on viewing angle. The quantity of pigment determines lightness by controlling scattering. combined effects internal order within each particle random orientation among particles...
Iron oxide nanoparticles are promising materials for many technological and environmental applications due to their versatile functionalization magnetic properties that allow a facile remote control, separation analyte recovery. In this contribution, the results of gold(III) sorption by naked DMSA-capped (DMSA = m-2,3,dimercapto succinic acid) magnetite discussed. Magnetite 8 nm diameter were first synthesized thermal decomposition iron(III) oleate followed ligand exchange reaction...
The XPS Fe 2p<sub>3/2</sub> core-level spectra of sodium hexacyanoferrate(<sc>ii</sc>) and nitroprusside.
Despite the potential of magnetic nanoparticles (NPs) to mediate intracellular hyperthermia when exposed an alternating field (AMF), several studies indicate that heating capacity NPs depends on factors such as cytoplasm viscosity, nanoparticle aggregation within subcellular compartments, and dipolar interactions. In this work, we report design synthesis monodispersed flowerlike superparamagnetic manganese iron oxide with maximized SAR (specific absorption rate) evaluate their efficacy...
The thermal-induced changes in molecular magnets based on Prussian blue analogues, M(3)[Fe(CN)(6)](2).xH(2)O (M = Mn, Co, Ni, Cu, Zn, and Cd), were studied from infrared, X-ray diffraction, thermo-gravimetric, Mössbauer, magnetic data. Upon being heated, these materials loose the crystalline water that enhances interaction between metal centers, as has been detected Mössbauer spectroscopy At higher temperatures, a progressive decomposition process takes place, liberating CN(-) groups, which...
XPS appears to be an excellent probe for exploring the coordination chemistry in metal acetates.
Pillared ferrous 2D tetracyanometallates, Fe(L)2[M(CN)4] where M = Ni, Pd, Pt, and L is pyridine its derivative, form a family of Hofmann-type coordination polymers. This includes members...
